Error "Error processing the TurboTax file! Please make sure that this is a 2017 TurboTax file and the file is not password protected."

When I started using TurboTax Business 2018, it suggested using online Quick Employer Forms (QEF), and I and I followed the instruction to get online. I chose my last year's file (xxx.tax2017) to transfer employee information because it says: "If you created your forms within TurboTax Home & Business 2017 or TurboTax Business 2017 last year, we recommend that you transfer 2017 payee information for ongoing employees - then all you have to do is update amounts for 2018."   Unfortunately, I keep getting the following error:

"Error processing the TurboTax file! Please make sure that this is a 2017 TurboTax file and the file is not password protected."
