I need a EIN number for 1099 Misc Form for the Minnesota Frontline Worker Pay. What would I put for the Payer's EIN?

You won't need a MN EIN if you enter the income as "Other Reportable income" in the "Less Common Income" dropdown.

At the bottom of the pages, select "Miscellaneous" and "Other Reportable Income."  Enter the description "MN Frontline Pay."
