My Chromebook won't upload pdf files. HOW can I see my 2021 forms that I've just completed? I think I may have the wrong figure for amt of tax paid!

I guess you mean download the pdf to your Chromebook?  Have you paid fees?  You have to pay to see the forms.  And it looks like you are in the Live feature for a higher cost.

 

To see all the forms you need to pay any fees first with a credit card.

To cancel you can just leave and abandon it without paying.  Or You can try to clear it.

With online TurboTax you do not get direct access to all of the forms until you have paid your fees.   You can only peek at your Form 1040:

Click on Tax Tools on the left side of the screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

 

 

As already explained---if you want to see any of the other tax forms or worksheets you have to pay first.   Or you can clear it and start over wherever you want to.

You need Adobe Acrobat DC reader installed on any computer for it to read pdf files.
