Sorry for your loss of you dad
first, if you dad passed away in 2019 his estate would not have received anything and if it did, the IRS required it to be returned....so your Aunt is correct.
Now on to you...
First, CAN anyone else claim you in 2020? you didn't state your age, who you are staying with, whether you work or not, etc, which can make a difference in whether someone CAN claim you. IF someone CAN claim you in 2020, you are not eligible for the stimulus.
But let's assume for the moment, no one CAN claim you, here is what has to happen.
In the end, the stimulus is really about the 2020 tax return - your filing status, your income and any of YOUR dependents. Nothing about 2018 or 2019 matters.
On the 2020 tax return, it will calculate what you are eligible for (probably $1800), then it will subtract what you have already received ($-0-) and will provide a tax credit on LINE 30 of the tax return, which has the effect of increasing your refund by $1800 (or reducing what you owe)
So can you confirm what your situation is (in school?, age?, income over or below $4300? who is paying most of your support (rent, utilities, etc.) and if you are not a dependent of some one else, all you have to do is file a 2020 tax return
make sense?
