The amended return button is not working. When I select it, it just signs me out. I tried to clear the cache and history. Still not working. Any thoughts?

For what tax year are you trying to amend?  If 2022 you cannot amend a tax return that has not been filed or if filed accepted by the IRS.

What tax year are you trying to amend?

I’m trying to amend 2020. It logs onto the screen for a split second and immediately logs me out. 2021 works without issue. Only 2020 has the issue. 

Have you tried using another browser?  If that does not work, please reach out to TurboTax Support for assistance via this help article: What is the TurboTax phone number?
