Master Limited Partnership reporting is complicated if done correctly, and even more complicated when all parties are not on the same page.
I will provide some comments:
1) Thankfully this will be the last year you have to deal with this as I believe Teekay has elected to be taxed as a C corporation effective January 1, 2019.
2) You should not be double reporting the same information. Make sure you are understanding exactly what is being reported on the K-1 vs the broker statements.
3) In general, MLP distributions are not dividends. Take a look at the broker statement. Many broker statements reflect amounts, however, if you read the statement it indicates (in some sections) that this information is not reported to the IRS. So some amounts are reported to the IRS and other amounts are not reported. So as noted in comment 2, double check your broker statement to make sure you understand which amounts are actually being reported to the IRS.

Also keep in mind the date of replies, as tax law changes.
