Caution:

The taxpayer should have notated the appropriate 2020 tax period for which the payment was being made. All payments made towards the deferred liability should have posted to the appropriate 2020 tax period in which the deferral was made. If, when the payment was made, it was erroneously credited to a 2021 or 2022 module, transfer the payment to the appropriate 2020 tax period.

The deferral of the employer’s share of social security tax for the quarter was entered on Form 941, Line 13b and posted to the module as a TC 766 with CRN 280. The TC 766 CRN 280 "credit " transactions posted to communicate the deferral amount reported on the original return and TC 767 CRN 280 debit transactions reversed the credit as payments were received and applied towards the deferral or when the payment of the deferred amount became due (i.e., December 31, 2021 and December 31, 2022), whichever was sooner.
