Did you buy it in the store or online? I buy mine online.
If you bought it in the store do you have the 16 digit License Code? How to get started with the Desktop program, install and activate it

If you bought it from Costco Online.....
I'm on Windows 10. Here's how mine went.
1/3/25 Bought Home&Business from Costco online. 20 min later got email with License Code and download link. Clicked on Download link. It took me directly to Turbo Tax to download. Had to pick my product then select Win or Mac. Program downloaded.
Had to go to my Downloads folder. Clicked on downloaded .exe file. It started but stopped saying I needed Microsoft Visual C++ with an install button. I clicked on it and it installed the MS Visual C ++. Then it continued to install Turbo Tax.
Checked on the License Agreement. Clicked on Install. Minute later it was done and launched.
Sign in to Intuit Account, had to get email code to enter.
Got License Code screen. Went and copied 16 digit code from email and pasted it into code box.
Got into program.
First thing I did was check for updates. Then I always go up to Online-Updater Preferences and check Ask me before getting updates.
