There is a "fault" in the online filing system where self-employed cannot file through schedule C and system is requiring a employers EIN. Anyone else experience this?

You should not be required to enter an EIN for your Schedule C unless you have employees.  

You may be experiencing an issue similar to some other users where you are being asked to enter an EIN for a Form 1099-NEC instead of for your Schedule C.  If you think that is what might be happening, use the following steps to eliminate any unused Form 1099-NEC from your return:

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “1099-NEC” and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to 1099-NEC”
• Click on the blue “Jump to 1099-NEC” link

This will bring you to the summary of all Form 1099-NEC that you have entered.  Click Delete or the trash can icon next to each one.
