second stimulus

I filed my taxes and my fed was accepted on the 12th of feb turbo asked if i had got my stimulus and i answered that only the 1st, they asked how much i was estimated to recieve or something like that- and nothing from there and i assumed that was good and then on the 15th of feb i received a letter at my old address stating that my stimulus had been sent out via direct deposit. So my problem is that, i havent seen my stimulus and also the amount is incorrect being that i had a child the year of 2019 its missing the eip for 1 dependent. its to my understanding that i need to file this recovery rebate? So how do i go bout this now? since i already filed?? I paid for max benefits for this pls thanks! i also havent received my fed that was estimated on the 5th
