Filing status of original return and filing status as amended

TINs from the return, Name control, date of birth, date of death for each TIN and what credit was claimed for each TIN.

A ‘Y’ under a credit indicate that it was claimed on the original return. An ‘A’ indicates that it was later added and a 'D' indicates it was deleted.

If the TIN on the original return was invalid, ‘INVLD SSN’ will be displayed under the SSN/AMEND column, and if the name control was invalid, a ‘*’ will be displayed next to the name control. A 'x' in the credit field indicates that it was disallowed when the return was filed.

To add a new claim, enter the claim received date into the highlighted input date field. The date is automatically populated by the command code if the latest amended return date is available. Otherwise, 'YYYYMMDD' is displayed. Hit TRANSMIT when the cursor is on the 'ADD' field to initiate the add request. If the change is for the same claim previously entered, use the 'EDIT' option next to the previous entered record to edit the record instead of ADD.

If any prior claim was entered for this return (up to 4 with the latest first), they would be listed below the input date field. The claim received date and category code are listed for each record. To view a previous entry, move the cursor to the claim received date of the desired record and hit TRANSMIT to display the validation result screen for that record. To change or delete the most recent record entered, move the cursor to the 'EDIT' or 'DELETE' field on the screen and hit TRANSMIT.

If there is a L freeze or TC290 on the module, or if there is a 2/10 year EITC ban on the account or if the tax period is old, the input to the command code will be disabled. **STOP** will be displayed instead of the date entry field.

To add a credit claimed, enter an ‘A’ under the EIC, Exemption/DEPD, CTC, CCC, EDCR, or ADPT CR field
