Your account has a minimum NEAR balance based on the storage you are using on the NEAR network. If you enabled 2FA, the minimum balance will be around 3.5 NEAR.
If you have a lockup, this account will have a 3.7 NEAR minimum balance.
If you enabled 2FA and have a lockup, the total minimum will be around 7.2 NEAR.
You can reclaim this NEAR by disabling 2FA, and by transferring all of your NEAR out of your lockup account (after your lockup period has ended).
