With a General Category rank of 14 Lakh and an SC Category rank of 139,657 in JEE Main, it's highly unlikely you'll get into a NIT or GFTI through JoSAA or CSAB counseling for a desirable branch. Your SC rank is within a range where you might find a seat in some NITs or GFTIs, but likely in less competitive branches or in the later rounds of counseling. You should explore options like state government colleges and other universities through their respective counseling processes.
