Your ETHW wallet address is the same as your ETH address, just on a different chain now. So whatever you had before the merge, you have 3 times now - on ETH, ETHW and ETF. You can see what you have on ETHW by searching your address here:

(Note: They JUST changed the ticker symbol for ETF to ETHF!)
