Get your taxes done using TurboTax

Why after I’ve e filed both state and federal taxes are the amounts owed different. Both were accepted but the amounts owed are completely different from when I filed/ paid. I already paid what turbo tax told me I owed and now there is a 300 difference for both state and fed. How can that be. Also I uploaded pics of 1099s and then after I paid I had to manually put all the info in. I’ve been a lifelong TT user but no more. Terrible product
