After you file

Thanks for the quick response.

I receive a check every 2 weeks. I went through all 25 check stubs for 2022 and added the federal tax that were withdrawn from my employer and it adds up to the box on my W-2 form but it was my first time for 2022 to have an additional $100 withdrawn from my check every 2 weeks which would up to $2500 which is not accounted for on my W-2. My question is where should I have placed the $2500 on my 1040 form?
