I had to file an amended 2025 Tax return using Turbotax home and business 2025 and it didn't allow me to amend my Colorado state taxes? How do I amend my Colorado state return?

See How do I amend my state tax return?

Hopefully, you made a copy of your original federal and state before amending. You always want to keep a .pdf of your taxes with all the worksheets.

Yes, I have a copy before I amended the 1040.  However, I then amended the 1040 ie created a 1040x to include a Colorado K-1.  So I filed the 1040x to the feds and the Colorado 104 to Colorado.  Then I received another Colorado k-1 so I amended my 1040x and could not amend the Colorado 104.   

I have tried the link you mentioned with no luck :( Thoughts ?

Oh I forgot to say ' Thank you! '

So the link above didn't help. 

However, I went to FORMs and opened a 104x Colorado Amend tax form.

And it was all filled out ! I didn't expect that.  I had to make some modifications and add some items to the form but it was nice to see !  It beats having to fill out the form by hand. 

However, the bad news is that the Colorado.gov/revenueonline site will allow you to amend your Colorado 104 tax form and it worked easier than TurboTax, probably since it was only a Colorado k-1 change?  

And what is going on in Turbo tax regarding calculating taxes?  Turbox tax said approx $200 was due vs Colorado online said $500 was due ???  Any one have any ideas why the difference?
