TT should be able to handle both state tax returns and all applicable forms. I can't tell you whether you are better off preparing manually; some individuals are comfortable following the TT prompts and figuring out the forms by reading the state form instructions as they are preparing the returns and others just struggle.
Based on what you have stated, the Utah return should be pretty straight forward since the most important schedule for you would be the TC 20 Schedule J with everything reflected in column B.
In looking at both state tax forms, if you are only going to prepare one state return using TT, I would probably recommend preparing the Colorado return with the software.
