I submitted the I-130 on the 23/nov/18..0n the 18/Apr/ 19 I got a notice to provide more evidence does it mean dat my previous fee/evidence is lost?

If you received a notice to provide more evidence, that means that U.S.C.I.S. has already received your case and is only asking for the additional evidence at this time. Your fee has certainly not been lost, and you should check carefully to see what U.S.C.I.S. is requesting to ensure that the evidence that you initially provided was sufficient. If you believe that it was, you can send it again, but I note that U.S.C.I.S. usually asks for evidence because it is not satisfied with what was originally submitted.
