Thanks for the quick reply. In my case, I don't need to amend the taxes as the IRS simply wants me to re-resubmit due to a missing ID verification check (CP63 notice).
Do you know if TurboTax will allow me to e-file again? Looks like that is not an option for prior years: https://turbotax.intuit.com/tax-tips/irs-tax-return/how-do-i-file-back-tax-returns/L535BxMms
