How and where on 1040 do I indicate that I worked without a salary for the whole 2019 as the solo entrepreneur in the c-corp startup that I founded?

[A11L64]

In late 2018, I founded a startup and incorporated it as a C-Corp. There were/are no other founders and also no other employees, except of course me as the CEO. The startup did hire some people/firms for some tasks (like setting up a website, legal guidance, etc) but they were paid immediately by check by the startup. In 2019, the startup had no income or revenues. I did not take a salary and the startup did not pay me anything and hence no W2.

Now I am filing my 1040 as a joint-married filer and wondering where/how to report my status.

Thank you for any help you can provide,
