Oil well drilling operation started in late 2020. We received drilling expense invoices late 2020. No production and no revenue was reported or distributed in 2020. We did not receive income until 2021, thus no 1099-MISC in 2020. I saw in a previous reply that deductions could not be taken until a 1099-MISC, 1099-NEC, K-1, or some other document was received from the drilling company. Can the initial drilling expenses in 2020 be be taken along with the 2021 expenses?
