I plant in compost all the time. If it's still hot, I'd turn it a few times and let it finish before planting seeds into it. Turn it twice a week and it'll be ready in a month.
My standard potting mix is 40% finished and screened compost, 40% sharp river sand, 20% normal soil from the garden. It drains well, has a ton of microbial life, and doesn't cost me anything. I've got a source for river sand where I get about 10 big 5-gal pails of the stuff (the outside curve of a river). That usually lasts me for 2 years.
It may be too hot because there was too much manure in the compost mix. If that's the case, it'll burn your baby plants, even if the compost is cool to the touch. You might be smart to scratch it into your soil and inch or two before planting into it. You'll still get all the benefits of the compost (microbial life) but it'll be integrated into the soil that the plants will eventually
root into.
"The rule of no realm is mine. But all worthy things that are in peril as the world now stands, these are my care. And for my part, I shall not wholly fail in my task if anything that passes through this night can still grow fairer or bear fruit and flower again in days to come. For I too am a steward.
