Transamination or deamination of amino acids helps their carbon skeleton into the cycle directly (as pyruvate or oxaloacetate), or indirectly via the citric acid cycle.

Default Involvement of AA into TCA cycle

AA can get into gluconeogenesis through TCA cycle.
Also Urea cycle - from FA "Amino acid catabolism results in the formation␣ of common metabolites (e.g., pyruvate, acetyl- ␣ CoA), which serve as metabolic fuels. Excess ␣ nitrogen (NH 4+) generated by this process is converted to urea and excreted by the kidneys."
