turbotax home and business limiting my solo 401K deduction?

[cmomed]

Hi TT community:

I have a solo 401K (with both Roth and traditional accounts)  and am over age 50.  I have net profit (income) from my self employment business of $122,000 in 2024.

For 2024, I am making the following contributions as both employer and employee:

Roth 401K elective = 17500

elective traditional 401K =5500

catch up traditional 401K =7500

employer profit sharing (20% of net income) = 24000 

By my calculations, I should have a retirement deduction of $37000 ($5500 + $7500 + $24000)

BUT turbotax says that my retirement contribution allocation is $35790

I have no other business entered , so not sure why the deduction is reduced to $35790 , or why Turbotax had to do an "allocation"?

I have done many solo401k contributions in prior years with Turbotax and this is the first time this has happened?

Am I doing anything incorrectly?

Thanks for help!
