Franchise Tax Board is saying I may have missed a payment

[bobmd007]

The Franchise Tax Board sent me a letter stating that I may have not reported money that was paid to me via credit card transactions. They say SHIFT4 (which is my credit card processor) reported some payments. How can I tell if those were reported on my 2020 Tax Return or not? I can't find an entry for that, or any other 1099 income. Can you help me figure out if I reported it or not?

Thanks, Bob

Sounds like that should show up as income on federal Schedule C.  Check Schedule C line 1 for the total payments you received.

Thank you, VolvoGirl. I do see that number on line 1 of my Schedule C form. It appears to be the grand total of ALL my 1099's added together. Is there anywhere in Turbo Tax or my completed Tax Return where it shows the individual 1099 values so I can see if I missed anything? 

Second question, if I missed something, can I go back in and Amend my 2020 Tax Return? 

Thanks, Bob
