Go into the techadvancing config menu and look at the right-most tab there.
You can access this either by clicking the Techadvancing reserach icon in the top right corner of the left-window-part of the *vanilla* research screen. (This left part also shows the research description and the progress)

Or alternatively, if you are for example using a mod that replaces the vanilla research screen you can still access it via the mod-settings menu while playing on a map. This is located in the escape menu in the game settings i believe.

thx see it just blind
