I’m concerned the amount of state income tax I owe is incorrect, what’s the best way to calculate if it’s correct? Or is it best to consult and agent?

WHY DO I OWE STATE TAX?

We cannot see your tax return.  The most common reason for owing state tax is that you did not have enough state tax withheld from your paychecks during the year.   Double check all of the amounts you entered from tax documents such as your W-2's---look carefully at boxes 16 and 17.  Look for misplaced decimals and extra zeros.  Print a copy of 2023 and 2024 state returns and compare them side by side, line by line to spot the difference(s).
