The amendment(s), proposed by Ted Cruz (working with DJT) and sponsored by 6 other Republicans, were introduced to both the 115th (2017) and 116th (2019) Congress. As you stated, Congress as a whole did not favor the amendment and thus it was defeated both times.
This was the amendment as written:
Rather than trying to find supporting documents for everything he ever said in a left wing, GOOGLE biased world of information, I urge you to go to this GOVERNMENT ARCHIVE site to look at the list of his actual accomplishments.

But the Orange man never introduced a Constitutional amendment for term limits in the first 100 days as President as he promised he would do. As the article you cited described “his campaign” promised to propose terms limits, but once he got into office, his promise made was a promise forgotten.
He lies as casually as other men draw a breath. I doubt that he even knows when he is lying, and instead prefers to deny facts or label things as “fake news.” He now your President. The felon and liar in chief who promises to get tough on crime (except his, of course).
Do you have any idea, at all, how amendments to the Constitution can be introduced?
TDS.
Make sure you pray for Trump’s soul next time you kneel at the altar of the Saint Joseph Biden.
Supreme Court “INJUSTICE” SKAMala Hair…something! 
would NOT be good! They just don’t quit. Now they want to throw this “MONKEY WRENCH” into the system. Throw any 
at the wall that’ll stick. 
Just for damage control. 
Give the American people one last f-u, only the democrats could pull off something like that.
You forget about the Senate Majority Leader position. The RINO’s will be sabotaging that one, and THIS time, “We the People” will have NO say in it. Corrupt senators have no choice but to keep Rick Scott from obtaining the position, lest their own corruption becomes investigated. Trust me, this will be a slam dunk for the RINOs.
