Can I have my accountant fill in the taxes for me using my account? I filled in most, and I want to have it reviewed and possibly filled in a few entries.

If you choose to give your accountant access to your TurboTax account and user ID, that is your choice.  Do be aware that TurboTax is not licensed for use by paid preparers.

It is violation of the Terms of Use for a paid tax preparer to use TT.

And the accountant should refuse to do that IF you are paying him for his time.

Well, here the accountant is my brother-in-law. I am not paying him. He offered to review it.

I have a solution. I will print and have him review the printed copy. I suppose that is legal.

That is a horse of a different color.

You will need to pay your TurboTax fees before you can print.

I already paid the price for turbotax. I can print.
