Seeking Advice on E-Filing Challenges

I am attempting to file for an uncontested divorce in Texas, but there is not a clear option for divorces with children in the e-filing system. I am in full agreement with my ex, and we want things to go through without a hitch. For our scenario, the e-filing system is unclear and does not provide guidance.

Has anyone else in Texas had to deal with this? Could you file for an uncontested divorce online while having children? I am concerned that making the incorrect choices could make things more difficult. I would be very grateful for any guidance. Would you kindly give any hints for using the electronic filing system?
