In the column "place of work in the questionnaire" write "unemployed" or "housewife". A copy of the labor can not be a confirmation, you need either an account statement from the bank, or a sponsorship letter plus a certificate from the sponsor's work, a copy of the first page of the Russian passport of the sponsor; A certificate of birth is required to confirm kinship.

Refusal in the visa because the sponsor works in an organization that has been sanctioned is unlikely.
