Get your taxes done using TurboTax

It is not on 1040 line 31. That field is blank. How will I get the $16,000 dollars back if I don’t file an amended return?  I paid Estimates of $8,000 (2021) and ($8,000) (2022). They show on the worksheet but not the 1040. I don’t want the time to expire to file amended returns. Last time I did that it took them three years to pay. They did pay with interest. Is there any harm filing amended returns?
