MBG006.A0101.TF1 is J2b-L283>>Z615>Z597
Unfortunately the coverage is not good enough for something more specific and I do not currently have time to check it thoroughly. But he is negative at: J-Z1297, J-Z631, J-Z38241, J-Y75277
Given the above information, and considering we have I4998; Hungary_IA_LaTene_o, north of the Balkans, I would say he is likely under J-Y15058 but not under J-Z38241. In all likelihood, a Cetina culture derived lineage since the oldest J-Z597+ samples come from this culture as can be seen in the J2b-L283 ancient DNA map.
