I have TurboTax 2021 that I run on an iMac. In attempting to submit my federal taxes online I get two identical error messages: "Schedule C (Writing Biochemistry Textbooks -D) Other Expenses Text is invalid for Electronic Filing. Please remove all preceding spaces invalid characters."
I have been unable to fix these errors. I suspect that it has something to do the Olympic and Paralympic box in Schedule C. How can I fix these errors?
