1099-R no payer's state number

So I made erroneous Roth IRA contributions in 2020 when I had no earned income, but withdrew all my contributions and earnings in February before the filing due date (April 15, 2021). I won't be receiving my 1099R from Vanguard until next year in 2022, but I need to file this year since I owe the 10% penalty tax on my earnings. The 10% early withdrawal penalty on my earnings is the only tax I owe.

 

I complicated things by requesting federal and state withholding when I removed my contributions and excess. Now TurboTax is asking me for the Box 15 Payer's State Number but I don't have the information since I won't be getting the 1099-R until next year. I want to e-file my return but I can't e-file without the Payer's State Number. I've seen this thread suggesting that I input the payer's federal EIN in replacement.

 

What is my best course of action?
