Under normal circumstances, this type of request can be expected to take 8-12 weeks and you could track it by calling the IRS service center. Currently, the IRS call centers are closed and staffing levels are drastically reduced so you can expect processing time to be increased dramatically - however, exactly how long it may take is not known.
Unfortunately, at this time there is not a good way to track the status of this request. However, I would not have expected an update or even an acknowledgment within two weeks under even the best of circumstances.
