What numbers do not match? your terse question/comment is not clear.
boxes 1a and 1b "might " match each other, but 1b can be lower than 1a....box 3 has nothing to do with any of them.

But if your paper 1099-DIV is different form what was imported from the broker...that can be due to several things. Make sure you have the most recent 1099-DIV form from the broker...the brokers sometimes update their 1099-DIV forms at a later date, especially if you have holdings in RE investments that do not report until March. So get the "Final" 1099-DIV for 2018 from your Broker, and make sure the numbers on that match what is in your tax file.
a) IF you have not yet filed your 2018 tax return, then just edit the numbers to match. BUT...talk to you broker to make sure if they are different so you make sure you have the final copy. b) IF you Have Already filed your final 2018 tax return some months earlier, and have already received your refund (or paid additional taxes owed) then you will need to amend your 2018 tax return and print/mail in the amended tax file paperwork yourself to correct the changes.
