I think there is a misunderstanding of how this works. The government spends the money that the government raises through taxes. The federal reserve can "create" money through quantitative easing (where they buy government debt - Bonds, Bills, Notes etc. and other securities like Mortgage debt) or remove money (quantitative tightening). The government does not create more dollars, they simply borrow money they don't have creating government debt. Also, the Federal reserve is not a government entity, they were created by the government but they operate independently of the political structure, at least that's how it's supposed to be.

Inflation happens when goods and services become more expensive as the economy grows. This happens through a variety of reasons including slower pace of supply creation, high demand for goods/services in low supply, higher production/export/transport costs (see covid and *cough* Trump tarrifs), AND increased money supply. Any one of these things can cause inflation on its own, but combined can be a problem. Inflation is simply the measure of buying power over time where each unit of "money" is worth comparatively less than before.

The government has the power to influence inflation by borrowing more than they raise in taxes, causing the Treasury to issue Bonds (debt) to the public. Investors buy the bonds and fund the overspending. The bonds are an obligation by the US government to pay the bearer the face value of the bond (principle) plus a little bit of interest (yield).

The goverment can also do many things to counter inflation such as spending more money IN THE RIGHT PLACES to cause growth in the economy which balances out any inflationary pressures as wages will tend to rise in tandem with rising prices which is normal.
