It is Jan 25 and I'm still getting an error message when I try to roll clients forward into the 2019 Tax Program. I tried updating my 2019 programs, but that didn't make a difference. I don't do organizers, I just want my data in the tax program!
You do start this in 2018 not 2019. Highlight the clients then look for the icon 18 -> 19 to do the proforma. There is often a problem if the client is locked (stupid Intuit has still not fixed). Be sure to back up all clients > Unlock > do Proforma
