Retirement tax questions

This is what is happening to me.  By mistake  I had the amount of RMD taken out twice. But, it’s telling me I didn’t pay it completely and it’s penalizing me over $800!  What is wrong with your calculations?  My 1099specifically says it was paid in full, however you say I did not.  I’m not willing to pay your exorbitant prices in order to talk to someone that probably knows less than I do about taxes!  Also I’m over the amount where I am exempted from taxes and you are charging me a 29% rate, what’s up with that! I am 77 years old in retirement and have been filing with Turbo Tax for many years but something is very wrong this year.
