If you used the Online version you should always save both the PDF file and the tax data file each year (before online closes Oct. 15) so you have a copy when you need it like for a loan or if you ever need to amend it in the future. You shouldn't rely on getting a copy from Turbo Tax. Or if you want to use the Desktop program next year so you can transfer from this year.
