I know the feeling
basically you have to add it in macrodroid directly, you really only have to open TouchTask once to give some permissions.
Add macrodroid action - Tasker/Locale Plugin - TouchTask - Read screen - (you can set some constraints here but i would just leave it as is, atleast for now) click the check mark in the top right to continue.
In the next screen you will have to create some variables to save the outputs, just click the + signs to create a new (local) variable for each field, i believe the actual text is saved to "Element texts"
I see the screenshot of your macro now, i will take a look at that, if you want to give the TouchTask method another go just try that in a new macro ok, don't try to place it somewhere in this one
