For my knowledge, 2 theta should fall in between 20 and 26 degree and it could be broad or a small peak depending on the amount of oxygen or defects. I tried to figure out that and that 's what I have got from published data. Also take into account that not necessarily you would get the same plane in electron diffraction or d-spacing from HR-TEM analysis.

It should be round 23 , 2 theta degree. And the peak intensity will be very small and broader
The question is a good one. We get only a single peak between 20 to 26 degree as rightly pointed out by Khaled Habiba. This peak is near to plane of hexagonal graphite which peaks at 25.6 degree in XRD.
I wanted to add something for my answer. Usually, all the people who published shows the plane (002) in graphite, which depends on the quality of the graphene structure that you have. Also, if graphene is dopped with nitrogen or another element it could change a little bit beside the defects and amount of oxygen if GO was used in producing the GQDs. I have got in electron diffraction the plane {1100}, which is about 0.214~0.213 nm and other reported another plane in GQDs 0.242 nm corresponding to the plane {1120}. So it is possible that you will get the diffraction of these planes in your XRD diffractogram.
