You will need to take the RMD as soon as possible so that you can inform the IRS that it has been taken.
You will need to file a 5329 form (attached below) and request a waiver of the penalty that would only be denied it you intentionally ignored the RMD or failed to take in prior to filing the 5329.
From 5329 instructions:
"Waiver of tax. The IRS can waive part or all of this tax if you can show that any shortfall in the amount of distributions was due to reasonable error and you are taking reasonable steps to remedy the shortfall. If you believe you qualify for this relief, attach a statement of explanation and file Form 5329 as follows.
1. Complete lines 52 and 53 as instructed.
2. Enter “RC” and the amount you want waived in parentheses on the dotted line next to line 54. Subtract this amount from the total shortfall you figured without regard to the waiver, and enter the result on line 54.
3. Complete line 55 as instructed. You must pay any tax due that is reported on line 55.
The IRS will review the information you provide and decide whether to grant your request for a waiver. " [From: https://ttlc.intuit.com/questions/3869970-form-5329-for-rmd-penalty]
