she must have some ingrained bad habits to not be potty trained at 1 yr old.

If she is sleeping in the bed with you or hubby- she should be removed to the floor and given a nice little bed on the floor.
{ it's a alpha dog thing- you humans need to be the top dog- and the top dog doesn't let the lesser dog share it's bed}

we had the best luck using the bathroom as the potty area - no food in there & papers covering the floor

you may have to go back to potty training like with a puppy.

as soon as they wake -you take them to the potty area
after they eat - you take them to the potty area
before bed - you take them to the potty area

is there no garage or back yard available ?

here's a link to some great books & videos in libraries -
