I need to amend already filed and accepted 2021 return because I forgot to include 401k direct rollover distribution from a former employer (Form 1099-R). Since the entire distribution was directly rolled over to an IRA, there is no taxable income associated with it. Therefore, no change to the tax liability. When I start the 1040-x amendment, the "meter" does not revert back to $0. The cause is that it's showing an incorrect amount of standard deduction for the original return (shows $80 less than what was reported in the original return). Why is this happening and how do I fix it? Thank you all.
