What kind of company? It matters. Parntership? Multi-member LLC? S-Corp? C-Corp? Joint Venture? Something else?
Overall, it is apparent that you do not know the intricacies' of a business owned by more than one person. There's no such thing as a "loan" from an owner. It's a capital investment. I would' HIGHLY recommend you seek professional help ASAP, especially if 2018 was your first year of business as a multi-owner company. Do note that the company tax return is due March 15th, and the late filing penalties are expensive, at $200 per owner per month. Fines and penalties for reporting things incorrectly can add up fast, and wil make the cost of professional help seem like a pittance in comparison.
Please seek professional help. Otherwise, you risk falling in with the 85% of new businesses that fail due to bankruptcy because they didn't do the taxes right that first year.
