How do a answer a 1099 misc for plasma donations (BioLife) when I do not know the payer's EIN or which box to put the compensation in?

It doesn't sound like you got a 1099-MISC.  You may have other income.

If you don't have a W-2, it can be posted to Other reportable income. 

Start at Federal

1. Wages & Income.
2. Scroll to Less Common Income.
3. From the drop-down select Miscellaneous Income [Select / Revisit].
4. Choose Other income not already reported on Form W-2 0r Form 1099.
5. Follow the Interview.
