Is 2210 being ignored by IRS a known problem? IRS want amended 1040 filed, but 2210 I filed is correct. Should I refile identical return? or will that just confuse IRS?

Problem is for 2021 1040. IRS says found computational error. What they did was totally ignore the 2210 and assess underpayment penalty. Turbo Tax prints 2 Page 3's of the 2210, one filled in, one blank. Could that by confusing IRS? How stop filing the blank pg 3?
