Unemployed helps my son with housechores and he gives me money. Does that count as taxable income? Does that count towards min income for obamacare marketplace insurance?

I am 67. just moved to USA (Virginia) in 2023. unemployed.
If I report the pocket money my son gives me in Turbo Tax, it gets taxed as self employment. If I don't report it, I am worried that marketplace will make me pay back the credit because my income was lower than my estimate when signed up
