Yes, enter this year's form manually if it did not transfer in. You will come to a question that asks if she attended this school the previous year, answer Yes. It doesn't affect any of the calculations on your return.
But, are you sure it did not transfer in? Within the Education summary, there are student summaries. You may be looking at a screen that is only referencing your son. Make sure that both students are listed on the Education Summary. When you click to edit or review the entries for each student individually, you may find that the 1098-T did transfer with your daughter's info.
To view the Education Summary screen, search for education and use the Jump to education link. The will take you to the Expenses Summary. You should see both students. If you click on Edit next to the student name, it should should the 1098-Ts that transferred in.
The only reasons that I can think of that would prevent you seeing the previous form is that you removed her and then re-added her for some reason or maybe on the dependent screens, you said she was not a student....maybe.
