The sum of the deductible portion of self-employment taxes and the IRA contributions shown on Schedule 1 is not permitted to exceed the amount of wages shown on Form 1040 line 1. The amount of wages shown on Form 1040 depends on the amount of the $19,000 allowance actually spent on housing. The deductible amount of self-employment taxes depends on whether or not self-employment tax is being paid on the housing allowance.
With the contribution limit for someone over age 50 being increased to $7,500 for 2023, the $15,000 of combined contributions for 2023 put you over the compensation available to support the contributions. That would not be the case with the lower maximum contributions permitted for past years.
