Amended 2020 now need to ammend 2021?

I never received a 1099-R for a 401-K withdrawal.  Thus forgetting to include it with my 2020 1040.  I amended my 2020 1040 and submitted 1040X.  With the 1040X I submitted 8915-E Qualified 2020 Disaster Retirement Plan Distributions and Repayments.  I selected to spread the taxable amount over 3 years.   I have two questions:

1.  Turbo Tax printed out 2021 Form 1040-ES Payment Vouchers.  I'm guessing I need to send in those payments ASAP because they were due in 2021.  This leads into Question 2.

2.  How do I amend my 2021 1040 using Turbo Tax where Turbo Tax knows I amended 2020?  And how does the Payments get accounted for? And how does Turbo Tax know about the spreading of Tax over 3 years.
