Topic tags/keywords: gap filling caulk joints

I just put an extension onto the bottom two stair treads and risers in my basement (wanted the bottom two stairs to be a little wider than the others. Now that it’s all nailed, glued, and screwed, there are some up-to 1/4” gaps between some boards.

Any advice about how to fill those gaps? Liquid nails? Wood filler of some sort? Some caulk or spackle?? Appearance isn’t important, as it’ll eventually be covered in carpet.

Clearly, it’s a high wear, prone-to-flex area—your advice is appreciated!
