A 5329 will not be generated if there were no excess contributions. They were removed timely and you indicated the taxable amount on the Form 1099-R is zero (box 2a). It's not yet clear of the year printed on your Form 1099-R(s).
There is nothing to amend since the money was removed and there were no earnings to report or pay excise tax on (Form 5329).
As indicated by @dmertz and @fanfare, based on your comments there is nothing to amend for 2021. Dividends in a Roth IRA will not be reported on Form 1099-DIV at any time. Distributions will only appear and be reported on Form 1099-R. Only your regular brokerage account will report dividends earned.
The code descriptions you requested are:
8—Excess contributions plus earnings/excess deferrals (and/or earnings) taxable in 2022. (If there is any taxable amount in Box 2a.)
J—Early distribution from a Roth IRA, no known exception (in most cases, under age 59½).
