Getting error using Import Wizard to insert data from excel, csv, or txt into an existing DB

I know there's a lot online about this and I've looked at a lot of it, but I'm not sure what options to choose and I dont know why I get this error. Furthermore, we have a heavy "figure it out on your own", "respect other's time" culture here so I don't want to ask. Now I've wasted a day.

Part of what I did and what happened:

Refreshing SQL Server DB:

I: Truncate or Delete DB:

II: Importing from xls to SQL Server DB:

  A: Right click on Database (not server or table).

  B: Select: Tasks > Import Data

  C: Choose source.  Flat file is probably best because the software for that is standard. I’m not sure if CSV or TXT is better.Which is best?

D. Choose destination:

I’m not sure which is best. Which is best? My guess is one of the first two, but I tried all four and nothing worked.

I though this information would help me select a destination, but it did not.
