how do i send bitcoin from my watch wallet only to my standard wallet
Bitcoin isn't stored in a "watch-only" wallet or a "standard" wallet, it's stored on the blockchain. Wallet software, such as Electrum is a piece of software that interacts with the blockchain, it doesn't actually contain the bitcoin. Your "watch-only" and your "standard" wallets show the same information that they obtain from the blockchain, so both should be able to display the bitcoin associated with your public and private keys (respectively.)
A "watch-only" wallet is incapable of sending bitcoin because it doesn't have the ability to sign transactions. If you restore your wallet using the seed phrase (you should have written it down on paper when you created the wallet) you'll be able to sign transactions, and send the bitcoin wherever you like.
