Manager called me after I called out of work.

I work from home and for calling out there's a specific # to call before hand. I called the # and called out, just wanted a day- soon after calling out my manager called me a few times (didn't answer) and texted saying to call back when I can. Im prob overthinking, I just really don’t feel like calling back. Should I just text saying I needed a day be back on tomorrow or something similar?
