I signed the consent to disclose my information, but now have changed my mind. How do I reverse or cancel that?

To cancel the Consent to disclosure of your tax return information that you signed, the tax return has to be cleared and started over.

If you have not paid for the online edition you are using, have not filed your tax return or registered the Free edition, then you can clear your return and start over.  Click on Tax Tools on the left side of the program screen while working on the 2019 online tax return.  Click on Clear & Start Over.

That worked, thanks!
