Hi @Amy3217
Welcome! Love your place!
If you just went live with your listing, Airbnb says it can take up to 72hrs for it to appear in guest searches. This allows a Host to update important sections of the listing before guests can book it. Things like House Rules, Cancellation Policy, Calendar Settings/Prices, etc. Additionally, not sure if I understood about your search using dates for an entire year? Ony listings that have availability for an entire year will appear in search results. Looks like you have a 3night min stay and the calendar is blocked until October. Try searching for your listing using a 3night min in October in the next day or two if you just published it:

"After you publish your listing it should be visible within 24 hours. But it may take up to 72 hours for some listings to show up in search results."
Photos
Noticed you only had a few photos? Most Hosts have at least 25-35 photos. Always a good idea to add captions to every photo as well. This helps guests understand the "story" of your property and all the spaces they will see both inside and outside.
