If that is the first time you've used the 2FA to send... based on the amounts you have specified, I would guess that you have just prepaid for 20 (0.0002 btc) 2FA credits as per TrustedCoins current charges:
https://api.trustedcoin.com/#/electrum-helpPay every 20 transactions: 0.0001 BTC/tx 0.002 BTC total
Pay every 100 transactions: 0.00005 BTC/tx 0.005 BTC total
If you click the little blue shield in the bottom right corner, you'll see how many credits you now have remaining. Your next lot of 2FA transactions (equal to the number of credits you have) will be not cost extra until you run out of credits and need to prepay again.
