Retirement tax questions

I'm 75 and my MRD for 2019 was $21K but I decided to increase that to $100K, ( $80K stock, $20K taxes). which I transferred as Stock to my standard stock account. The broker reversed the transaction, advising that opening a Roth was a better move as I didn't need to cash out. I expected therefore to see a 1099-R with $100K withdrawn and $20K taxes paid, but the 1099 showed $100K as Normal Distribution with $20K taxes taken plus a Roth Conversion of $80K for a total distribution of  $180K

Entering the Gross Distribution as $180K shows that I owe almost $40K additional taxes, but I only took $100K distribution on which I paid $20K tax, How do I show that all I did was roll the initial $100K back into my IRA and then move it to the ROTH
