First of all the download is not the same as the Online version. It is the Desktop program. You can install the Desktop program either with the CD or download the program.
The Online version you go online and log into each time through your browser. It is totally different than the installed Desktop program. Then you can log into online from any computer or device.
In the Desktop program you aren't saving your entries to Intuit. The return is only saved on that computer as a .tax2021 file. It should be in your Documents then in a Turbo Tax folder.
And you can't use the Desktop program on a mobile device unless its a laptop running Windows.
Your plan won't work unless like I said you copy the .tax2021 file each time to the other computer. You only have 1 current file.
