TT imported wrong Payer TIN address on form 1099-DIV How can I edit at "federal Review" step?

the only required info is the Payor and the amounts on the 1099-Div lines.  wrong address doesn't matter. that info is more for the taxpayer's use than anything else and is not sent whether mailed or e-filed 

In order to correct the entry/import error in TurboTax Online, you can exit Federal Review by going back to the list of menu options on the left side of your screen (the dark-colored bar) and selecting Wages and Income. There, you can scroll down to Investments and Savings and select the Form 1099-DIV with the import issue to make any needed corrections.

Once you have finished all of your entries, you can run Review again.

See this thread for another discussion regarding how to fix errors during Review.
