slimandlam,
The TurboTax solution https://ttlc.intuit.com/community/taxes/discussion/1099-div-box-9-how-to-report/00/134868 shows how to treat the RSU cash liquidation. If, as I assume, you did not pay anything for the RSU's, your basis in them was zero and you treat the distribution as a long term capital gain.
The 1099-MISC is a problem. I recommend that you attach a PDF statement of explanation to your return that includes (a) your name(s) as shown on your return, (b) your SSN(s), (c) the tax year (2019) and Form 1040, and (d) Subject: 1099-MISC statement of discrepancy. The body of that note will show exactly what you have reported here: that the company issued you income forms 1099-DIV and 1099-MISC that duplicated the same income and you are appropriately reporting the 1099-DIV income as a capital gain.
