1099-NEC with no state

Hello! I live and operated a business in WA state, as a webhosting company, for a client in TX, and he sent me a "combined tax statement for forms 1098, 1099, 5498 1099 -nec copy B" and it only has rows of blue and white lines. Under the column for IRS BOX #, it has 2 rows, "1" and "7", Nonemployee compensation, and State Income, and both amounts are the same. No state is mentioned. I understand neither WA nor TX has a state income tax, and my tax prep platform website has a dropdown box for a state to choose for boxes 5-7. Should I leave the tax state dropdown box empty since there's no state abbreviation on the 1099-NEC composite form and since, if I'm right, there's no need to designate either state since it's a moot point for state tax returns in any case?
