Can't transfer USDT TRON to Spot wallet due to network fee!

Hi guys, completely new to Binance and crypto and completely defeated by this app!

Have acquired some USDT by way of TRON by way of p2p. Now I'm making an attempt to move this USDT to the spot wallet but I maintain getting that I can't because of the network charge! Apparently I want some TRX to perform this, although all of the docs I learn say this shouldn't have any value!

In the app I'm doing this by going to Pockets (change from Change/Walltet) -> belongings (bottom proper) -> Send -> Switch to binance change -> choosing USDT TRON.

Appart from this, the opposite drawback is that when making an attempt to transform some USDT to TRX to cowl this charge, I can't resulting from similar purpose! I want some TRX within the stability to carry out the conversion.

On the photographs you'll be able to see my USDT stability (it exhibits!), what I attempt to do in the transfer and the message I get once I hit "switch"

I'm a bit misplaced here and doubtless I'm doing one thing else mistaken. Any help is appreciated!
