1099- Misc and Box 3

I have 1099-Misc income on my 1099.

 

I imported 1099 directly into TT and under

 

Wages and Income and then 1099 Misc, when I clicked on Update it is showing me 2 1099-Misc from same brokerage.

 

One item has correct item already filled out in Box 8

and other one says needs review and nothing is filled.

 

I assume I just delete 2nd one? Not sure why it TT software is showing 2 1099 - Misc?

 

1099-Misc (Box 8, substitute payments)  is Taxable amount? by which rate? your ordinary income tax rate?

 

 

What to do with Box 3 in 1099-Div? It is NOT taxable amount. I assume it is for information only as your cost basis will be reduced by this amount?
