Paul used Scribes to write his Epistles (Letters)
Evidence
Paul composed his letters in accordance with the writing conventions of his time. Scribes were essential as the skills required for writing with primitive pens and paper made writing legibly a challenge.
Tertius was one Roman Scribe ('Amanuensis') who wrote on behalf of Paul. Tertius wrote Paul's Epistles (letters), either from notes, ideas or direct from Paul's mouth. At the end of the Epistle (letter), Paul would conclude with personal greetings in his own writing. [John Gill's commentary]
Timothy is present as Paul and Tertius write Romans. Did Timothy have any influence over the final text? If so, what was that influence? Was any text in Romans written by Timothy?

I, Tertius,
the one writing this letter for Paul, send my greetings, too, as one of the Lord's followers
Paul, write this greeting
in my own hand. Remember my chains. Grace be with you.
I, Paul, write this greeting
in my own hand, which is the distinguishing mark in all my letters. This is how I write.
I, Paul, write this greeting
in my own hand.
Timothy, my co-worker, sends his greetings to you, as do Lucius, Jason and Sosipater, my fellow Jews.
