Connect your wallet if you haven't already. You will first deploy the metadata carrier contract, which is a contract that contains your DAO's metadata information. Next, you would confirm the origination of the actual DAO contract, after the metadata carrier contract has already been deployed. And finally, after the DAO contract has been deployed, you just need to wait for Homebase's indexer to pick up your DAO's contract.
After your DAO has been properly indexed, you will see a button that says, "go to my DAO". And if you click on it, you will be taken to your DAO's page.
A DAO fails to deploy every 2 out of 10 times because of a beacon-wallet bottleneck. On Ghostnet we've switched to a managed flow where we just take your parameters and deploy it for you, but we didn't implement this on Mainnet yet. You can try again using another wallet and/or browser. Alternatively, if you provide us (in the Homebase Discord) with the info in the summary page (last screen before deploying), we can put it onchain for you. The wallet that executes the transaction doesn't factor into the functionality of the contract, so it doesn't really matter that it's not you signing.
