Retirement tax questions

I just deleted the 1099R, let TurboTax reimport from my brokerage.

 

Program hardly asked me any questions at all, accepted the RMD amount and increased my taxes due by several thousand dollars.

 

Please, I need step by step instructions on how to get this entered correctly so that I do not send in an error ridden tax return showing thousands of $$$ in taxes due when I do not owe any at all.

 

Do I need to start a new return?
