State tax filing

TurboTax allows you more than ten entries on Schedule M, Step 3, Line 13. Once you reach 10, use the slider bar on the right to add more entries. TurboTax will create an additional information sheet to list the other entries.

As an alternative you can type "See statement" on the Account Number and Contribution Amount fields and attach a separate page with any additional amounts.

See the Line 13 instructions on page 2 of 2021 Schedule M IL-1040 Instructions.
