Cares Act IRA Rollover of Stock Removed as Part of RMD

I rolled over a partial RMD of stock from my IRA account and returned to original account. Brokerage firm did not show the value of the rolled over stock as equal to th at of the distribution. Brokerage firm showed the value to be that of the stock on the day of the rollover. Therefore the rollover deposit does not equal the original dollar value deposited in the IRA. Brokerage firm only matched the number of shares originally withdrawn. In other words the rollover matches the number of shares but not the dollar value. Brokerage firm refuses to correct the the dollar amount of the rollover. Therefore I will not benefit from the Cares Act that allows rollovers in 2020. What is my recourse?
