With TT Premier on Windows, I tried - again - to delete form 2210. It didn't go away, but TT took me down a path toward error check and asked to download an update. I did that and .... I got past the error check and they SAY I'm ready to file. PROBLEM is, there is still a form 2210 checked and all, just no error. I KNOW I paid 110% of my previous year's taxes and also I'm getting an $8K refund...SO... it shouldn't generate form 2210 at all, seems to me. Anyway, I give up - I'll just mail the stupid thing in without adding Form 2210. I really do hope they fix it the right way instead of just removing the error on the fact that Part II, Box A is checked so I can efile. I worked in software before I retired and fixing the error this way is the stupid, lazy programmer's way to get their boss to just say - hey you fixed it!! good for you!! (But not for us)
