You have made two mistakes in Step 3.

i. You did not tweet in reply to https://x.com/CoinMasterRace/status/1828890173939085357. Instead you posted on your profile.

ii. You did not remove '<My_PulseChain_Address>'. You just added your PulseChain address after this.

Please correct the above two error and then execute Step 4. I'll send your $SEC payment after that.
