Retirement tax questions

@DanaB27 

thank you sir. I played with the TurboTax software and find the following hack. If I choose the option to pay the due by mailing a check instead of direct debit from my bank, then TurboTax software allows me to e-file the amended return for 2020. Then instead of mailing a check, I can go to the https://www.irs.gov/payments website to pay my due online which is much faster. 

Do you see a problem doing the above?

 

thanks you for all the help, appreciate it.
