Utah Resident works in Colorado - W-2 is "irregular"

Hi Lisa - Thank you for responding. W-2 has a line for CO and wages of 56633 box 16 and SIT 2240 box 17. Next line State UT with wages 17467 box 16 and SIT 90 box 17. All wages (56633 box 1) earned in CO. I don't know what the 17467 represents for UT but employer says W-2 is correct. Taxpayer does receive travel pay to commute to CO of 400/mo. He works 2 wks on and 2 wks off and goes to UT where his family lives on off weeks. Total wages = 56633. ProSeries adds state wages together and makes UT wages 56633 + 17467 = 74100. Did Part Year residents on both returns. I did fill out dates of residency in each state on the Federal information worksheet. 

UT instructions state UT residents who earn income in other states must pay UT tax on that income. W-2 says 17467 but according to that statement shouldn't that include the CO income of 56633? UT residents then claim a credit for income tax paid to another state if that income is taxed twice. How is the income properly reported?
