Where do i find if i received a penalty fee or not for underpayment on my Federal taxes. where can that penalty amount be found in my return?

Check line 38 of your Form 1040.

You need to make quarterly payments using the payment vouchers if you make a profit greater than $1,000.

Thanks. Yeah that is grayed out. So i went to form 2210 and that said no penalty because my withheld amount was more than the max required annual payment based on prior year's tax. Cool.  That works.

Or you can have more taken out of pay... raise withholding %.

Form 1040-SR row 38 (Amount You Owe) will list the penalty you are paying. Also, the turbotax cover sheet that prints with the tax breakdown has it listed.

Thanks, yeah, not there so wasn't penalized.  Also, form 2210 goes into detail on it.
