For Forms U2 and U4, you may copy and paste or enter data starting at row 21, columns A, and C through H; and Form F3B starting at row 22, columns B and D through H. For the available, utilization and total columns, you must click the “Check the Data Before Submitting” button in the upper-right corner for these columns to calculate.

If that does not work, you may find detailed instructions in the NRUF Non-Geographic Job Aid located here, https://www.nanpa.com/nruf/requirements-file.
