It's still not clear you understand what happened or what is supposed to happen.
Here are two ways to handle when you inherit part of a house from a parent.
Method 1. The estate of the deceased parent sells the house. (An "estate" is a legal entity that carries on the business dealings of a person after they have died. Your parent's estate may have only existed for a few months to close out their business. The estate of someone famous like Michael Jackson can continue for years or decades to manage the income from their copyrights and other property.)
If the estate sells the house, the estate must pay any taxes. The estate must pay all of the other lawful debts of the deceased (credit cards, last utility bills on the house, phone and cable bill, past-due property taxes, and so on.) If there is any money left over, it is distributed to the heirs. In this case, the heirs receive money, and pay no tax on that money (*there are rare exceptions to this.)
Method 2. The house is sold by the heirs, not the estate. The heirs report the sale of the asset and pay tax on any capital gains. If you inherited 1/3 of the house under state law or the operation of a Will, you pay tax on 1/3 the gain, even if you did not receive 1/3 the proceeds.
Not it is not clear to me, how you the heirs, could legally sell the property without an estate, and be paying off taxes. (By taxes owed, I think you probably mean property taxes on the house.) It could very well be that you owe more than your proceeds, if the transaction was done incorrectly. (For example, if the FMV of the house was $100,000 when your parent died, and it was sold for $160,000, then each of three siblings has a $20,000 gain. But if, because of outstanding mortgage, interest and property taxes, you only received $4,000, then your tax on $20,000 gain could be $3000, leaving you with almost nothing.
The taxes should have been paid from the estate, and if the only asset was the house, it should have been sold way earlier so as to preserve any value it might have had.
If the house was sold by method 1, you don't owe any tax, unless some part of the estate payout to you is taxable for an unusual reason.
If the house was sold by method 2, you would report 1/3 the cost basis, and 1/3 the selling price, and pay tax on 1/3 the gain, assuming you are a 1/3 beneficiary.
I still think you need to see a tax attorney to make sure everything was done correctly and that you understand how everything was done.
