If I worked at turbo tax how do i obtain Turbotax payer ID number ?

What type of Form 1099 did you receive?  There are almost two dozen different types, 1099-NEC, 1099-MISC, 1099-R, 1099-B, `1099-S, 1099-INT, 1099-DIV, etc.

Were you an employee and received a W-2 or were you self-employed and received a Form 1099-NEC?

The payer ID number is on the Form 1099-NEC or Form W-2 that Intuit sent you. (The name of the company is Intuit, not TurboTax.) If you don't have the 1099-NEC or W-2 you have to ask your contact at Intuit how you can get a copy of it.
