Lisa - 

You are correct,with the update the 2018 works like it should - if you check the 2018 box 

My major gripe is that from 2006, the 1st year on the 1040X was the current year. Now for 2018 the 1st year is 2019 - made no sense especially when you had to check the 1st box (2019) to get the 2018 data 

Before we noticed the change we amended a 2018 Colorado not noticing the 2019 box was checked, so Colorado did what we told them (in error) they amended the 2019 return using 2018 numbers. 

Thank you for your input
