"The 1099G is issued to the company EIN."

Yes; these are Business Grants. Unless that specific grant is specifically named in some law that exempts it, it is Business income and subject to tax reporting the same as any other business income.

"Agree that the link does not work from the 1099G worksheet to the Schedule C."

And you don't try to Link it. Informational Reporting of business income can include 1099-G and 1099-NEC, neither form is entered into your business tax return, but Both of which are a part of the business income to be reported for that business.

The same thing applies even if there was never a 1099 issued at all. You still report all Business income for the business return.
