Full 1099 w/ S-Corp, do all employer contributions apply for me?

[Sean H.]

I saw something recently where the CARES act added in last year that an employer can contribute up to 5,250 each year until 2025 towards student loans, and the money becomes a full write off.  My company is just me and partner, with no "employees."

I am already aware that i can contribute to a solo 401k as an employee and employer. But, wasn't sure with other contributions i can play the duality as well. 

Does this also work with health insurance copay?
