If you have no income in 2019 then there is no reason to file a 2019 tax return.

You must have at least $1 of income on a tax return to get it accepted. Instead of trying to file a return, go to the non filer portal and enter your information. This will register you for the stimulus payment: https://www.irs.gov/coronavirus/non-filers-enter-payment-info-here
