From non customer businesses. There are online applications open at chase and Bank of America. I also found an online application at lendio.com.

The application is pretty simple but there are required document that might be a challenge unless you are a big enough business that you do a formal payroll and have the records.

My first impression is that many of the most needy small business are simply not going to have an easy time applying for this relief. While the help being offered is noble, This is very likely to go down as another bungled government program with massive waste and fraud.
