After you file

Why must I install Turbotax forms updates after I have filed my returns?  Is it possible that these changes will change the tax returns that I have already been filed? Why is it so difficult to find out what the form updates are about?  It sends us out to the community where it is virtually impossible to find the answer.

When I have Turbotax Business and Turbotax 2018 on the PC, why does Turbotax Business open when I select my personal return from the desktop?


You do not have to update after you filed your returns, but it certainly is possible (although not probable in most cases) that your return(s) could change. 

 

There are a considerable number of updates and most of the information regarding those updates is simply not released by the developers.

 

TurboTax Business and the personal income tax prep versions share the same extension (.tax2018 for the 2018 tax year). Although the programs can co-exist on the same PC, clicking on the extension (or shortcut to the tax file) will result in that file being opened by either the personal version or Business edition depending upon how the extension is designated to be opened in Windows.
