If you don’t have vocals yet, what are you using as a guide/backing track?
will sort my own recording space
That’s a right-up-front big deal because we can’t take reverb and echo out. Once you record in the kitchen, it’s always going to sound like your kitchen.
Two possibilities are the back of your car and the kitchen table sound studio.
After you have a clean track and export it as a protection WAV file, then go for the effects.
Effects > Limiter
Effects > Compressor
Effects > Echo
Effects > Reverb
Last time I used echo as a voice effect, it was an adventure because the designer used a metaphor of clapping on one side of a canyon and then coming back in ten minutes for the return echo. Less useful when what you really wanted was stadium or large venue sound.
Others may post with ideas.
Do you have good, wired, sealed against the head headphones? It’s rough to follow the backing track without that because most of the other possibilities either don’t work well, have delay, or leak backing track to the microphone.
You can set up Audacity for Overdubbing. The Scarlett should do that. Listen to yourself at the same time you sing to yourself. You have to plug the phones into the Scarlett for perfect overdubbing, not the computer.

Or you can fake it with one earphone muff.
