Your daughter is likely just transitioning to some new abilities and likes. Over the next few months, she'll likely develop a little more ability to play independently, which should help you out some. Just be sure to give her some practice with entertaining herself (I speak from experience as with my oldest I entertained her too much and at 7 she still needs more help finding something to do than her younger sisters do). Try setting her up with a few toys and letting her play (and sometimes fuss) alone for a few minutes, gradually increasing the time you leave her alone. Be sure to make it short at first though - like mommy has to put this away/go to the potty/etc. and will be right back. I'm not saying to expect a child at any age to be able to entertain themselves all day, but giving them a chance to do so for short stretches of time is in her best interest as well as hers.
Anyway, there are also other things you can try to introduce to keep your daughter entertained. She can probably color some now. At that age, mine tended to like standing while coloring, so I could tape a piece of paper to a box or low table and give them a few crayons (fat ones usually easier to start with). You can introduce color names and let her get creative without a big mess. Most kids will just scribble for quite a while, but some will surprise you with their early artistic abilities. Just watch out for eating the crayons - they should be non-toxic, but if they get a chunk off choking is a possibility.
If you're open to a little more mess, you could also try play doh. A length of plastic sheeting will make clean up easier. Again, watch with the mouthing/eating.
Old magazines that you don't mind getting torn apart can also entertain kids. Pointing out familiar objects and giving names to things will also help with vocabulary building. And because you're really just looking at a wide variety of pictures, it sometimes keeps their attention better than a regular book. For regular books, though, ones that have flaps to lift, textures to touch, or (if you can handle it) noises to make are also much loved around that age.
To get out some energy, you could try Hulla Baloo. It's great for a wide range of ages, and while most 14-month olds won't necessarily get the right color/shape, they'll still enjoy dancing around on the pads, especially if mommy joins in with a silly dance. Or just turn on some music and have a "dance party." Or set up a hopscotch game with foam pads or even just tape on the floor.
My kids also love playing beach party - let them put on their bathing suits and sunglasses and lay out blankets/etc. to be the sand and water, play beachy music, etc. Really just anything different than the norm works.
Another one for getting the energy out is an obstacle course. Make it appropriate for her abilities, but climbing over couch cushions on the floor, going under a table, jumping aver a tape line on the floor, rolling a ball down a ramp or putting it in a bucket, etc. seem to work. Once she gets through it a mess of times, ask her to try it backwards.
Simple puzzles may start to work soon, and Little People are always popular here - mine have a ton of them and they're played with almost everyday.
Hope some of those ideas help. Just know that eventually it does get easier!
