In 2023, I contributed $2,050 as traditional funds to a Solo 401(k) and $8,000 as Roth funds to that same Solo 401(k). After entering my business income and expenses, TT tells me that I can contribute $14,636 of additional funds (see attached screenshot). However, I don't understand their calculations. How are they determining $16,686 as the maximum allowable and $14,636 as the remaining amount I can contribute?
