Has any startup founders filed forms 1120 and 100 independently (federal and CA taxes)?

Our situation seems incredibly simple: as a new startup, we've made less than $1,000 in 2020 and have spent way more than that (on advertising, cloud services, and contractors).

So working with a CPA seems like an overkill. We're trying to figure out the easiest and the quickest way to file these forms. As a new startup we don't seem to owe any taxes we just need to do the filing. And we have already paid the Delaware franchise tax.

Any suggestions? We'd really appreciate your help!

Thank you!
