i just found the answer to my own question online
in case anyone wonders, there is a form 2210 that you can use to annualize your income - show the IRS that you didn't not receive income regularly thoughout the year but rather in 1 or 2 lump sums, like for instance by sale of an assests. In turbo tax this can be done by opening your return and searching on underpayments of taxes
