Not to worry. Tulip bulbs normally are extremely easy to store.
Spread them out in a single layer in a well ventilated and dry, dark place. Keep away from fruit and other things that emits ethylene gas. Tulip bulbs are resistant to drying out, but high humidity is not good. Slightly below normal room temperature would be ideal at this time of year, but don't worry if it is a little warmer as this usually won't harm them. Throw away any that feels soft or lightweight. Plant when the soil temperature goes to 10℃/50℉ or earlier if they start to show signs of growth.
