@Ralph E FreemanIf you have established a Solo 401(k) with a reputable provider, they should be able to assist you with all of these very basic operational questions.If you have obtained a set of 401(k) plan documents with no meaningful support, then you should engage a CPA or attorney who is familiar with IRS rules and the operation of a self-directed retirement plan.
