Colorado State refund for 2023, MIA

I did receive a refund from Colorado for 2023.  However, the State reduced the amount from what was originally submitted by TT.  Working on 2024 taxes, the amount stored in TT is incorrect.  I did not receive a 1099G from Colorado this year and it seems impossible to contact the State to see what the actual refund amount I received.  Any ideas?  Thanks, Bob
