I underpaid. There is no 2022 Form 2210 or Form 2210-F. How to calculate this amount from 2022? Instructions for Line 8 is hard to understand. This thing has my 2022 return, why can't it calculate?
Last year's Form 1040 Line 22 is 0, no Schedule 2.
Refundable credits seem to all 0 also.
AGI for 2022 is not near the limits.
Single for both years.
2022 Income is only for latter 6 months, no income from first 6 months.
What should I enter in TT?
