Roth IRA form 8606

All,

 

Need some help on the Roth and backdoor Roth IRA!

 

I was stupid enough to make mistake twice in a row therefore there're  two questions.

In 2020, when our income was below the Roth IRA threshold of 196,000, we put 6,000 each in our IRA account. But I realized today that I didn't fill the 8606 form. How do I resubmit it? Do I just send the from itself or need to redo the entire 2020 tax.

 

In 2021, we can no longer contribute Roth so we did the backdoor IRA. I accidentally put the incorrect amount on form 8606. How do I amend that? Do I need to do 8606x? 

 

Thank you very much!
