I had this problem. Turbotax kept crashing when I went back and forth between Forms View and Fed Tax error check. Kept trying to find something to tell me why I had these errors related to a Business tax credit I knew nothing about. I became totally frustrated. One thing I googled told me I needed Premier to deal with K-1s, so I finally upgraded to Premier for $25. It didn't help at all. Now I'm really angry. Finally found this msg board that said just delete the whole form 3880. I'd tried to delete the contents of 3880, but not the whole form. Finally got the form deleted. In Forms View, find 3880, highlight and down on the bottom you can choose "Delete". All 15 of my errors are gone.
I'm a long term Turbotax user. Not likely next year!
