@ wills1970 and @ WoodyOne4U and others:
This might explain what some of you are experiencing:
We've been told the IRS just approved a lot of forms related to business returns today (1/28). Some are not yet available in TurboTax and will be in this week's update. Wait until Friday, January 31, then update and try to file.
TIP: And on Friday, do not try it right after it turns Midnight that morning. Wait until later in the day, i.e., during normal business hours on Friday, before trying. Be sure that day to get the latest updates for your software prior to filing.
