Get your taxes done using TurboTax

I am using turbo tax business on my windows desktop.  I am unable to upload my 2018 return into my 2019.  I click the upload button and the available files to upload are none.  That occurs when I am on Turbo Tax Files (*.tax2018).  When I go to All Files I can see the 2018 return saved but when I upload it I get an alert that says that it can't read this type of file. 

 

Please help.
