You might be entering it in the wrong place.
Enter the 1099G under
Federal on left
Wages & Income at top
Scroll down to 1099-Misc and Other Common Income
You might need click on Show More to expand the section
Then it's the first line for Refunds Received for State/Local Tax Returns - Click Start
You do not want the next line that says Other 1099G Income
On the first screen check YES - Received a State Refund.
But you might not need to enter it at all.
A State Tax Refund is taxable if you itemized deductions on that prior year's federal return and took a deduction for state income taxes instead of the sale tax. You got a deduction benefit for it so now you have to include it as income. If you took the standard deduction it is not taxable and you don't need to report it.
The software automatically enters the amount of the refund under the 1099-G worksheet. I never received a 1099-G but on that worksheet it is asking for the TIN. I can’t seem to get around it & I have tried looking up the TIN for Wisconsin dept of revenue without the answer. This is the last thing I have to do.
