Get your taxes done using TurboTax

TurboTax seems to occasionally do incorrect calculations!  When it subtracts my cost from my proceeds, it incorrectly gets a $3000+ Gain while is should be a $1000+ loss!!  This is simple arithmetic that a 7 year old child could do so why should I pay for a program that cannot?  I will NEVER use TurboTax again but since I am now almost finished with my 2021 tax return, what do I do?
