My understanding is the line is the sum of state and local income taxed I paid in 2019. that's it, but somehow, turboxtax added more than $4,000 on the line. What else did TurboTax add?
I have used TT for 10 years, so I checked all previous 10 years tax returns. The numbers on line 5a never match the total I paid for state and local income taxes. It was always couple hundred dollars more than the actual taxes withheld.
why??
