Just a note at something that jumped out at me.
I purchased a rental property in 2021 with a few other people,
This sounds like a partnership to me. Especially if there's more than two owners. I would highly suggest you report this as a partnership, since that's probably what this is. By reporting all rental income/expenses/depreciation on a 1065 partnership return, the totals of "EVERYTHING" is entered on "ONE" tax return. Then the partnership will issue each owner a K-1 for there share of the income/expenses/depreciation on the property based on their ownership percentage (which does not have to be equal for all partners).
Each owner will need that K-1 before they can even start their personal 1040 tax return. It makes life a whole lot easier - especially when it comes to selling the property, having partners leave the endeavor, or bringing new partners into this.
Take note that the 1065 partnership return has a due date of March 15th each year. At this point, I see no need to file a 1065 for 2021, and not just because it would be late and incur late filing fees if you did so. ($205 per partner, per month late).
The only things deductible on the 2021 return at this point is mortgage interest and property taxes, and those are a SCH A itemized deduction. Splitting that among all partners (3 or more I presume) would most likely not be enough to get any partner's itemized deductions above their standard deduction anyway, and would most likely make no difference in the tax liability of any partner on their personal 1040 tax return. But since I don't know that for a fact, you should just split the property taxes and mortgage interest paid in 2021, equally among all the owners/partners.
