Based on the fact that the attorney obtained a distribution to the estate, apparently the estate was the beneficiary of the IRA. If you were the designated beneficiary on the IRA, the estate had no claim to the IRA. If you were actually a designated beneficiary, the IRA custodian should have rejected any attempt by the attorney to obtain a distribution, so it seems likely that the estate was indeed the beneficiary and because the attorney obtained the distribution payable to the estate, you did not inherit an IRA, you inherited cash.
It's unfortunate that the attorney obtained a distribution from the inherited IRA because such a distribution is not permitted to be deposited back into an inherited IRA. To be able to be maintained as an inherited IRA the attorney should have requested that your share of the inherited IRA for the benefit of the estate be transferred directly to an inherited IRA for your benefit without making any reportable distribution.
Because the distribution is not permitted to be put back into an inherited IRA, the distribution is taxable. Presumably the estate will pass this income through to you to be taxed on your individual 2023 or 2024 tax return depending on the period covered by the estate's income tax return that includes this income.
