I 've received a corrected 1099-B consolidated form from brokerage, do I now need to file amended return?

Hello,

I've received a corrected 1099-B consolidated form for 2018 from the brokerage, listing 1 additional transaction.

Only thing it changed as a result is lesser short term loss amount on Schedule D line 7, resulting in lesser Capital Loss carryover for 2019.

Nothing is changed on 1040, no other changes.

Do I need to amend my 2018 return, and if I do, what do I file?

Thank you so much!
