If the question is, what do we do to be treated fairly, the answer is "see an attorney." There is no easy way now to deal with 20 years of ownership expenses.
If the question is, what do we do in 2025 to not make waves with the family, but get paid for our expenses, then you still need to see at least an accountant.
If the estate owned the home (and it was not owned by the siblings -- the title remained with the parents or the estate and it was never re-titled to each sibling as a co-owner) -- then the estate needs to file a tax return for 2025. The estate should list all expenses (from 2025 only, I'm afraid) against income from 2025. The estate should reimburse you for any taxes, fees, maintenance costs, etc. that you paid to maintain and sell the property. This reimbursement is tax-free. If you are paid extra as a management fee, that is taxable to you. The estate tax return would show the income (capital gains from sale of the property), the expenses, and issue a K-1 statement to each heir., along with each heir's proceeds after expenses. The estate would also issue you a 1099-MISC (I think) for your management fees, but not for reimbursements for estate expenses that you paid.
If you already issued checks to the other heirs without thinking about your expenses, it may be hard to claw that back without hurt feelings. You need to talk to an accountant, or an attorney or maybe a different attorney if the one you used didn't already help you with this.
