I can't help but feel that Sasuke doesn't know that he has a daughter. That would explain why he's perplexed by the feelings that are reaching him and why he's been absent for 12 years.
I'm guessing that Sasuke and Sakura are married, but that Sasuke was called for a multi-year mission after consemating his marriage with Sakura. Who then became pregnant shortly after. It's probably related to Kaguya which would explain Sasuke lack of contact with Sakura. Or possibly, they have been in contact via letters, but Sakura is hiding the fact that they have a child so Sasuke doesn't feel bad for being absent.
I hope this doesn't happen, but the current evidence supports this hypothesis
