Get your taxes done using TurboTax
You can use the federal ID (Payer's TIN) in the state box, 10b.
TurboTax requires that if box 11 has a value, then boxes 10a and 10b must also have entries. Box 10a is probably the two-letter state code for your state. The filer identification number for box 10b is likely to be the same to the Payer’s TIN on the left side of the form.
