No, you can't make a claim for that equity you provided the corporation.  If, in the future, you dissolve the corporation, and there is still an amount due to you (Due to Shareholder) then you could make a claim on your personal tax return, but for now, no.  However, if later on, there is enough money in the corporation that you could withdraw the money you put in, then you can do so without including it as income on your personal return.
