I purchased the desktop version of TurboTax and did my whole return. I owe $, so I was waiting until April to actually file it. Now when I go back there's no record

First things First...if you are in a web browser, you are in the wrong spot.

Second:  Start up your "Desktop" software by clicking on the TTX icon for "TurboTax 2023"

Your prior-prepared file should show up immediately as a selection to "Continue"

IF it doesn't, go to the upper-left corner "File" menu item and select "Open Tax Return" from the drop-down menu.  Youi can then browse to the location where you already know your files are saved......file should end in ".tax2023"    (but not any file starting with a "~" .  That should only be used in an emergency...it's a temp backup)

Once you've opened your file, do an immediate "save" so that the file's location is saved into the main program. 

TTX shouldn't lose track of it unless you move it yourself.  There are occasional problems with folks who save their files directly on a cloud drive, or off computer USB-connected disk, so only save it on your main system's hard drive.

Another way to open your Tax Return is by navigating to the folder where your tax return is saved and with the mouse double-click the file name ending in .tax2023 or right-click it, then select the option "open with..." and then select Turbo Tax.
