You may look up any Bitcoin address and all Bitcoin transactions on an explorer such as, though not limited to, this one: https://blockchain.info/

However, you wont be able to send bitcoin from one address to another.

In other words, you'll have to think back and try to remember how you were using Bitcoin. Did you have a web wallet, a software wallet, a paper wallet?

Were you logging in somewhere online that gave you access to your bitcoin? If you were using software do you still have access to the same computer (or at least the hard drive)?

Do you have any related files or data on your computer or any information written down on paper? Do you have passwords, mnemonic phrase, back up files?

If you do have any of the foregoing please don't post any specific private details here or anywhere else online. However, if you do remember anything such as what wallet or website or public addresses and dates or how you acquired bitcoin that would be ok to share if you really need more help regarding what to do next.
