I'm using form 4797 to highlight the recapture of bonus depreciation/special allowance for a 2023 vehicle. However the form has some incorrect validation on line 34 with some unknown assumptions backed in.

For example, for a vehicle that had a cost basis of 80125, and I took a special depreciation allowance + other depreciation of about ~$57000, the straight line depreciation method with HY convention used to calculate recapture would be 10% (for 2023) + 20% (for 2024) totaling $24,037 however the form validation complains that this amount is "too low" because the total depreciation taken is $57000

What is the exact text of the review message you receive on Form 4797? How much recapture are you reporting?

The error is "Line 34 is too small". The straight line depreciation amount is $24037. Line 33 is $56983.

Just so we are clear ... you have not sold the vehicle, right? But it dropped to 50% or less which is requiring the recapture, right?

Where in the program are you entering this? The last I checked (but has been a while), I don't think the vehicle section dealt with that, but you had to go to the "Sale of Business Property" section (even though it wasn't sold). But maybe my memory is wrong.

Where is this error showing? In the vehicle section where you are trying to depreciate this year's vehicle, or in the section where you are entering the $33,000-ish of recapture?

That's correct, the vehicle has not been sold, just its utilization has dropped below 50% and this is done through the "Sale of Business Property" section.

The error is showing on form 4797 (line 34, "Recomputed depreciation" which needs to be recomputed using SL)

To clear this, make sure the Sale of Business Property section knows this vehicle is a heavy SUV. If you’ve already done that and it’s still flagging, use these workarounds:

Navigate back to the Sale of Business Property section (where you are entering the recapture).
Look for a screen regarding "Special Rules" or "Vehicle Information."
Make sure you indicated the vehicle is a heavy SUV or truck over 6,000 lbs.
