After you file

I am facing an issue when i attempt to amend my 2020 Tax.

 

I used Turbotax online for my 2020 tax return, I realized i need to make some updates so i am trying to amend online.

 

However, before i even make anythings that i immediately see i owe both federal and state (CA) taxes.  I am scratching my head to understand why this is the case as i never even made a changes yet.

 

Anyone experienced this?  Can you please share your experience?

 

Thanks
