No, it's ok, let's just talk it through. My first question is - do you think you'll need to extend the flooring either side also? Or can you crop it close enough to prevent that necessity?
Try adding a Levels layer, and move the middle slider on each of the three channels:
Red channel 2.50
Green channel 1.50
Blue channel 1.35
Then invert the mask and paint on gently where needed.
It's easy to talk glibly about "taking out the finger", but of course what we'd really need to do is "put face in place of the finger". So you'd need another photo of her face at exactly the same angle, to borrow from.
I'm so sorry, the Red Channel is too damaged to fix.
Your only option is to process this one in black-and-white. If you do so, I recommend using a Channel Mixer layer, check the "Monochrome" box, and enter 0/+50/+50 for the three sliders.
