[Captain America: Civil War] Natasha says "You could at least recognize me" to Bucky. Does she mean from "Captain America: The Winter Soldier" movie or from the red room days?

It's ambiguous, and probably deliberately so, but all the evidence suggests that she simply means "from that time you nearly killed me a couple of years ago".

The backstory Natasha gave in *Winter Soldier* implies that, in the MCU, she didn't know the Winter Soldier the way she did in the comics. But, on the other hand, absolutely nothing Natasha says should ever be assumed to be the truth; her most potent weapon is always deception and secrecy, and knowing the right thing to tell people to get them to do what she wants is a skill so practiced it has become instinct.
