I bought it through Costco so the download link was not helpful. Thank you for that answer! Any other thoughts?


Then you will have to contact Costco for how or even if you can download the software again from their website.

If Costco is no help then you will have to pay for the 2021 TurboTax software to amend the 2021 tax return.

 

Go to this TurboTax website to purchase and download prior year, 2021 thru 2019, desktop edition software - https://turbotax.intuit.com/personal-taxes/past-years-products/
