The single member LLC, which has been in existence for 13 years has an EIN, 8 employees, and receives 20 or more 1099's each years from health insurance carriers, and applied for the grant using the business name and the EIN.  The Schedule C shows the EIN.  IRS has had no questions thus far.  Can't help the fact the 1099G for the grant has now been issued under the EIN.
