Dear Friends, can anybody help me to transform my 2FA non-segwit account to P2SH Segwit ?

This is not technically possible. You cannot "transform" one type of address to another and automatically have the coins available. You would need to create a completely new wallet and then send all your coins from the original wallet to the new wallet using a "normal" transaction (and paying transaction fees etc)

In addition i have prepaided in Electrum App 100 further 2FA transactions (3-th party - company which co-working with Electrum) so I don't want to lose it from my current addresses.

This *might* be possible, but as the others have stated, you would need to contact TrustedCoin and see if they would be willing to transfer the credits from your old wallet to your new wallet.
