Separated couple filing problem

My separated spouse filed her own return via TurboTax, and said that the program forced her to file Single because she (we) have no dependents.

 

I am pretty sure that, since our divorce is not final and we just separated in September, that both of us should file Married... either Separately or Jointly... and we are opting to file Separately since I moved to a different state after separating and earned significant income there. 

 

I am convinced she needs to correct her filing from Single to Married-Filing Separately, and the problem appears to be with the TurboTax program not allowing it. 

 

The return has not yet been released to the IRS and her state by TurboTax because she used a different email address.

 

Is there someone she can call to help her with this, *before* the return is sent to IRS/her state?
