TurboTax does not need the 1099-NEC payer's address. The only fields that are required are the payer's federal id number and the amount of the 1099-NEC. There is no TurboTax field for the address.
We'd love to help you complete your tax return, but need more information. Can you please let us know if you are being asked for the address in TurboTax and where that is happening.
