Get your taxes done using TurboTax

I have received a couple 1099-MISC forms from exchanges that have given me staking rewards. I have not converted these coins back into US Dollars yet, however since I received a 1099 with the apparent value of the coins when I received them (?), I suppose I need to report and pay tax on them now...?  Even though I haven't converted to USD, or otherwise sold or disposed of these rewards.??
