The number being reported is twice as as the amount it should be, so please look for a double entry.
Look at the retirement income section to see if the 1099-R was entered twice, delete the extra one.
You can dig through your return or look at your form to find the second entry. Only report your Required Minimum Distribution AFTER you enter the 1099-R and only as part of the distribution.
Here is a link to delete forms using TurboTax Online (for Desktop switch to FORMS MODE on the top right corner )
