How best to handle a revised 1099?

I received a revised 1099-DIV from my brokerage account. I have not yet filed my taxes, so no worries about filling amended returns. Their paper packet includes the full set - with 1099-INT and 1099-B (which did to change)

 

I assume if it works like in the past, I will be able to specifically download this revised document - I enter a package ID and Document ID to locate it.

 

But I have seen 2 answers, which is the best way to handle this? Should I delete the original import and re-import again, or should I just go ahead and import this document and it won't double-count anything?

 

Thanks!
