What you have to think about is that the stimulus cheque stimulated price rises. Everything, going to the supermarket today is much more expensive than in 2020, buying a house is much more expensive today and buying bitcoin is much more expensive in 2020. So I would blame the stimulus cheque rather than thank it.
Although injecting money into economy like this always has its negative side effects but if you do some quick calculations you'd realize that the entire stimulus package program was too small to be blamed for the inflation situation today.
For example the checks people received was coming from a $2.3 trillion budget and it was only a small portion of that budget. The rest went elsewhere like $500 billion of it went into government loans to companies, $349 of it went into other loans to small businesses, $150 billion of it went directly to local states and governments.
Now compare that one time amount with the $1 trillion the US government has been printing every 100 days and you'll realize how miniscule that stimulus package's effect on inflation was...
