I underreported my quartly tax payments.
I filed an amended return correcting the amount I paid each quarter which was $300 more than I entered in my tax return
All seemed to go well until the end when Turbo Tax questioned why I was amending my return because there were no changes.
Checking the paperwork, everything looked OK and I was due a $1,200 refund.
It appears the Turbo Tax does not look at the quarterly tax payments to locate all the possible reasons for the amended return
This is FYI and ask that you forward it to your system development department as it took me
a couple hours extra to verify that there was a change but Turbo Tax didn't look in the right place.
