How do I upgrade or switch to a higher version of TurboTax Online?

You can upgrade or switch to a higher version of TurboTax after you've started your 2020 return.

To upgrade your version of TurboTax:

1. Make sure you’re signed in to TurboTax and are in your return.
2. Select Upgrade in the menu on the left side of the screen.
   • If you don’t see the menu, select the menu icon in the upper-left corner.
3. Select the version you'd like to upgrade to.
4. We'll prompt you to pay if you want to print or e-file your taxes. You can also prepay at any time:
   • Select File in the left menu. (Don’t worry, you don’t have to file taxes—this just gets you to the payment section.)
   • Select Start or Revisit next to Review your order.
   • You’ll see a summary of your order. Select View payment options.
   • Keep going until you see How would you like to pay for TurboTax? On that screen, select Pay with Credit Card.
   • Enter your credit card information and select Continue.
   • Once you’ve paid you can go to Tax Home to access your upgraded features.

I tried to get my W-2 forms from a place I worked in 2020 the employer I worked for won't give them to me and I need to redo them as well.

@Shadron01 If you are unable to get your W-2 from your employer, and you have your last paycheck info, you can create a 'Substitute W-2' in TurboTax. 

You will need to mail your return with Form 4852.
