No. Federal tax paid to the IRS is not deductible on their next federal tax return. You will not enter anything on their 2023 federal tax return about paying the tax owed for the amended 2021 return.
There are several states that allow you to enter the federal tax you paid on your state return--Alabama, Iowa. Missouri, Montana, and Oregon. If you are filing in one of these states watch for the deduction when you prepare their state return.
