NY State tax calculation error 2023

I e-filed my NY State taxes and got a letter from them which stated that:

1. They adjusted amount allowed as total itemized deductions on form IT-196 based on limitations, worksheets and information I reported on the form.

2. I claimed an itemized deduction on return that used the incorrect income limitation required under the Tax Law.

3. The taxable income reported reflected a computational error based on information reported on return

4. NY State tax reported reflected a computational error based on the NYS AGI and taxable income reported

5. Adjusted refund to reflect the computation as indicated above.

 

Is this a software error?  It reviewed and check my forms twice before I submitted it.  It was a $41.89 error.
