Definitely report the increase as soon as possible. There is currently a public health emergency in effect that is extending Husky coverage anyway. Since the PHE is extending the husky coverage in my opinion more than likely you will not end up paying anything back. Also Husky eligibility is based on current/ monthly income and eligibility doesn’t have much to do with tax filing other than your tax household size versus the federal poverty level. There are other programs that the annual gross income is the number being looked at but for Medicaid it’s the monthly / current income only that is taken into account.
