@jc19int while you get an answer from my colleagues @dmertz whom generally deal with tax-advantaged pension plans, I just would like to point out that because you are filing jointly and each having a separate Schedule-C, you each ,must also file Schedule-SE and pay 15.3% of your net business income ( less a small amount ) -- SECA ( equivalent to FICA except for employer sharing ).
Just my 2 cents.
