Caution:

Once a TC 150 has been posted to the tax account and the computer has reversed the CRN 299 advanced payment amounts, any CRN 299 amount with Reason Code 219 attempting to post to the module will unpost with UPC 306 RC 3. Any corrections to refundable credits allowed with the original return must be made with CRN 296 or with CRN 299 and any corrections to non-refundable credits must be made with a TC 29X and appropriate IRNs. Corrections made after the TC 150 posts cannot contain a RC 219. See the table in paragraph (2) of IRM 21.7.2.7.6, COVID-19 Related Employment Tax Relief and Forms 94XX, for more information on IRN usage for the 2020 Form 941, Employer's QUARTERLY Federal Tax Return.
