Where do I enter pass thru entity tax deduction on my federal return? The LLC I'm a part of paid the state taxes on the entity level, and that is supposed to be deductible but I can't find where to enter it.

Are the state taxes reported on a separate statement with your IRS Form K-1 (1065)?

Enter the payment at Federal / Deductions & Credits / Your tax breaks / Estimates and other taxes paid / Income taxes paid / Other income taxes paid in 2021 / Withholding not already entered on a W-2 or 1099.

Retain a record of the payment should the state tax authority question you at a later time.

Yes, it's reported on a sperate form that came with the K1.

So I'm entering it in the federal withholdings box, right?

Just to clarify: I also entered this on my state tax form and got the deduction there, am I also allowed to deduct it on my federal return? I was told yes, but it seems like I'm getting credit for it twice.

Yes, State Income taxes are deductible on your Federal income tax return. Follow the instructions above from Expert JamesG1 to report these taxes.
