Used wrong year 1040-V printed coupon

[brazos49]

I just mailed my payment due for my 2021 tax return (I filed electronically and the return  was accepted before I mailed the payment) and realized that I used the 1040-V coupon that had "2020" on it.  That coupon was with the 2021 1040-ES quarterly coupons the IRS sent me and I used it instead of the new one.  I believe I noted on the check that the payment was for 2021 Form 1040-V and the exact amount matches my balance due from my  2021 Form 1040.  Should I be concerned about this or will the IRS properly apply my payment to my 2021 balance due?  I don't owe a balance for 2020.

The data entry clerk will pick a year for you based on either the voucher or the year you wrote on your check.

If it is assigned to the wrong year, you will have, as my Mom used to say, a mell of a hess.
