It blows, not sucks.

I just replaced the 50A55-571 control board on my Train central HVAC and now the blower motor is running backwards. It's blowing out the returns. What did I do wrong?

likely nothing. If the blower was running backward it would not BLOW out of the returns. It would not move much if any air at all.
