I've paid for the funding of my parents' restaurant (I provided the capital for a percentage of the income). We started working with contractors in mid-2018 but didn't actually open till end of 2019 (because of a contractor stealing equipment and money).
We were told not to submit a Schedule-C for 2018 and to only account for the startup expenses and losses when we actually open.
So should I submit those losses and theft in 2019? Turbotax seems to think that since the business was registered in 2018, we already existed?
