Bug in New Mexico tax calculation

TurboTax is calculating the wrong tax due for my New Mexico PIT return. My New Mexico Taxable Income (line 17 of NM PIT-1) is 92,982. This is correct in TurboTax. However, the tax on that amount (line 18) is wrong in TurboTax. TurboTax says it is 4,147, but it is actually 4,148. Not off by much, but it is off. 

 

I discovered this because I filed my NM return on the state website instead of e-filing through TurboTax. The state website calculated a different tax due than TurboTax did. I checked against the rate table, which says the tax due for married filing jointly should be "$768 plus 4.9% of excess over $24,000". Sure enough, the state is right and TurboTax is wrong: 768 + .049 * (92982 - 24000) = 4148.12 ≈ 4148, not 4147.

 

If there's a better way to report a bug let me know.
