Assuming your input is interlaced NTSC and not telecined, it should either be signaling tff or bff.
Hybrid does show the detected input scan type on the Base-tab and under "Filtering->(De-)Interlace/Telecine->Deinterlace/Telecine Settings->Input scan type".
If your source is interlaced and you deinterlace to same frame-rate thus throw away half the fields it doesn't really matter.
Usually I would recommend looking comparing the preview for both, since especially for old content, sometimes one field is better quality than the other.
If your source is NTSC telecined, you should not use QTGMC, but for example TIVTC (you can use QTGMC in it for the deinterlacing of residual combed fields).
