How does this take make sense?

Trump was heavily pro $2k checks. So were most Americans. Trump isn't attacking Biden for offering $2k, he is attacking McConnell for blocking it.

Plus, the idea that $2k checks instead of $600 checks is "bribing" voters to vote for one party is ridiculous, because the whole point of voting is to vote for the candidate that benefits you the most. It's like saying people who are voting for Trump because Trump promised a better economy are being "bribed" financially to vote for Trump.

Now, it would be different if the democrats said, "we will give $2k checks to everyone who can prove they voted democrat". That would be illegal and definitely bribery. That's why it's illegal to take a picture of your vote.
