StreamTrain, I'll take a look at what you said.
FWIW, I was on the phone with TT regarding this a couple of days ago. The tax expert said the usual caller was asking why the amount due went to zero; she hadn't heard of it not going to zero. She was discussing this with someone in the background, but they were having trouble seeing my data. We were working it when my AirPods died, the call dropped and by then after hours for the help desk. They sent me an e-mail saying completed, but with a contact follow up number if follow up is needed, which it clearly does.
I made working copies of the original file with the results (note, TT has been fully updated).
Copy 1 - original unchanged return. Shows Fed due $7,028, State $2,609
Copy 2 - original with deductions corrected. Shows Fed due $8,321, State $3,441. Additional tax of +$1,293 and +$832 from original return (copy 1).
Copy 3 - is the original copy 1 with an amendment started, but no changes made. Shows Fed due $3,074 (not zero), State due $0
Copy 4 - original copy 1 with same changes as made in Copy 2, i.e., original amended with corrected deductions. Shows Fed due $4,367, State $832. The delta to copy 3 of +1,293 and +$832 is the same as the increase from simply revising the original copy 1.
Looks to me like there is a programing error that would have me over paying for the change by $3,074. I'll reply to the e-mail and try to follow up on-line when I have more time.
